NEW FLICKER FREE TRAILING DIMMER DMR.730 >> SMRD TECHNOLOGY Mains fluctuation immunity The light intensity adjustment in a common flicker free dimmer is usually based on IGBTs (Insulated Gate Bipolar Transistor). These dimmers have the ability to vary the conduction angle of the power supply sinusoidal voltage so that regulation of brightness variation of the lamp(s) is achieved. When IGBT is in conduction state it acts as a switch, and consequently the supply voltage is conducted at the dimmer’s output. This means that any fluctuation in the mains voltage is conducted to the lamps and the result is the variation of the lamps’ luminosity. Thus, these dimmers are flicker-free concerning their electronic circuit, but the lamps are flickering because of the dimmer’s weakness to control the fluctuations of the mains system. The new SMRD (Switch Mode Regulated Dimming) technology monitors the mains voltage and stabilizes the output voltage so that this remains stable and unaffected from the network’s fluctuations, thus results in the stability of the lamp(s) brightness.

When the IGBT is in conduction, the dimmer’s peak voltage (green curve) is about the same with the mains peak voltage (red curve). Consequently, the voltage that is conducted to the lamp(s) is proportional to the mains’ fluctuations.
The peak voltage of the SMR Dimmer (green curve), is stable irrespectively of the mains peak voltage (red curve). The amplitude of the mains’ fluctuation could be from 173V to 265V.
True output regulation Some dimmers available in the market achieve voltage stabilization by regulating the conduction angle. With this method the RMS voltage can remain stable, however there are three disadvantages: 1) Mains voltage must be always higher than the output voltage. 2) By changing the conduction angle, brightness is affected because the LED Lamp(s) luminosity regulation is depended on the conduction angle of the dimmer. 3) When the dimmer is on at full (conduction angle 100%), there is no possibility to further increase the conduction angle in case of a voltage drop from the network. SMRD technology maintains the output voltage stable with no need of higher mains voltage and without changing the conduction angle. This means that even if the dimmer is at 100%, the output remains at full (230V) in power supply voltage range from 173V to 265V.

A: Conduction angle 100%. RMS voltage is less than 173Vrms, not 230Vrms. B: Smaller conduction angle for output 230Vrms. The supply voltage must be higher than 230Vrms.
Changing angle A to angle B to maintain the same RMS output voltage, results in changing the brightness of the lamp.

More features of the SMR Dimmer: Inrush currents LED lamps but also CFLs (Compact Fluorescent Lamps) are usually loads with low power factor (cosθ=0.55-0.75). This means that the lamps’ peak current is considerably greater than the RMS current. Especially when the lamp is under dimming, the current at the start of conduction increases instantly at a great extent. This is the reason why lamp manufactures recommend the use of dimmers with 10 times greater power than the power of the lamps connected to those dimmers. The new SMR dimmer limits inrush currents, increasing the lifetime of the electronic circuits of the lamps, while it is also capable of handling it. Thus, the user can connect utmost so many lamps so that the sum of the power of these lamps is the same with the output power of the dimmer. Power Factor Independently from the lamps’ power factor, the new SMR dimmer consumes energy with power factor >0.98 (for output level 100%), without affecting the network. Lamp protection Due to the special electronic circuits and stabilization the output voltage is always steady and free from spikes and over-voltages protecting the lamps even from complete failure. Dimming law correction With the use of two trimmers the dead fields, that usually LED and fluorescent lamps have, are eliminated. The first trimmer is used for the minimum and the other one for the maximum brightness of the lamp. In this way the controller works correctly when adjusting the lamps’ brightness.
Master Slave operation The new SMR dimmer can work as master, controlling multiple SMR dimmers connected at its DMX output. With this feature, as many SMR dimmers as the user likes can be controlled from one controller.
CFL ignition CFLs (Compact Fluorescent Lamps) in order to ignite need operating voltage of more than approximately 50%. Thus, in order to turn on a CFL at 30% for example, the user should first adjust the dimmer over 50% and afterwards dim it at 30%. The new SMR dimmer is capable of providing a pulse of 100%, of the output voltage, for 1sec automatically, in case we need to turn on the lamps at percentages less than 50%.
Control inputs The new SMR dimmer incorporates both DMX-512 and analogue inputs. At the analogue input the user can connect 0/10V, or 1/10V, or rheostat 100Klog, or button for ON - OFF and dimming, or UP/DOWN button for ON - OFF and dimming.
PWM signal output The new SMR dimmer incorporates PWM signal output, providing the capability of driving constant voltage and constant current converters of ELECTRON SA. Thus, with one controller the user can control multiple types of lighting fixtures.
